CISC1600: Computer Science I Lab 7. 30pts

In this lab, we focus on practicing the use of string type and loops. You will design and implement a program that implements the conversion from base 10 (decimal) to binary.

Requirement Your program asks the user to enter a number in decimal representation, and then the program should display the number's binary representation.

$convert

Welcome to the base converter by X. Zhang!

Pelase enter the number:34

34 is 10010 in base 2.

Please recall the procedure explained in the youtube video. You can use the following function to calculate the exponents:

pow (2,8) will give you 2^8 (2 raised to the power of 8)
pow (2,i) will give you 2^i, for any given value of i

Note that the function gives you a double type, and you should convert it to int:

(int)pow(2,8)

Finally, to use the above pow function, you need to include one more header files in your program:

#include <iostream>
#include <math.h>
using namespace std;

int main()
{
...
}

Extra credits: You earn extra credit points for supporting other conversion such as the following:

How would you support the conversion between base 10 and any base smaller than 10 (base 2, 3, 4, ..., 9)?
Support for bases 16, i.e., hexadecimal, where every digits can take a value between 0 and 15, and we use A for 10, B for 11, C for 12, D for 13, E for 14, F for 15. For example, hexademical number 1F is 1*16+15=31 in decimal.

Example output for extra credits


$ convert

Welcome to base converter by X. Zhang!

Please enter the number:29

Please enter the target base:8

29 is 35 in base 8.


Example output 3

$ convert

Welcome to base converter by X. Zhang!

Please enter the number:31

Please enter the target base:16

31 is 1F in base 16.
